AuthorTopic: DDWRT routing subnet /48 - Need Help (Read 256 times)

I couldn't get any real help in the DDWRT, so I am reaching out to see if I can get more information on this matter.

I requested a /48 from HE. Need to subnet them to at least 3 different VLANs. I am using an example in the DDWRT WIKI]https://wiki.dd-wrt.com/wiki/index.php/IPv6%2C_6in4_tunnel_-_GUI_only] DDWRT WIKI that someone wrote, but it's for /64. So I am somewhat modifying for my needs. The problem I am having now is that none of my LAN clients can route through the WAN router. They all get IPv6 ip assignments. The DDWRT Router itself CAN reach beyond the Tunnel gateway and get ping6 replies.

using DHCPv6 to serve. My routed /48 is 2001:470:fxxx::/48 using subnet of 2001:470:fxxx::/64, 2001:470:fxxx:1::/64, 2001:470:fxxx:2::/64

This is a Broadcon SoC. So eth0 = CPU/SoC vlan2=WAN Ethernet port br0=local lan (default) and br1 and vlan6 are created.

It's possible HE has routing wrong on their side, but that's not likely.

I admit I only skimmed through your configs and didn't look at them thoroughly. Normally, if you're using your /48, you need to create a route on your side that sends that /48 to the inside interface of your router; this is needed because your router doesn't have an address in that /48 For example, the outside interface of your router might use 2001:db8:1234:5678::1 and the inside might use 2001:db8:1234:5678::2 If your /48 is 2001:db8:abcd::/48, your router has no idea what to do with it until you tell it where to route it. (If you've already done that, I apologize for telling you something you already know)

For example, the outside interface of your router might use 2001:db8:1234:5678::1 and the inside might use 2001:db8:1234:5678::2 If your /48 is 2001:db8:abcd::/48, your router has no idea what to do with it until you tell it where to route it. (If you've already done that, I apologize for telling you something you already know)

Don't be sorry. Because this is something that I thought about. I have tried issuing this at the router:

ip -6 r add default via 2001:470:c:1xxx::1/64 dev ip6tunip: an inet address is expected rather than "2001:470:c:1xxx::1/64"As you can see ... it gives me a syntax error.

But then again looking at the route table...I don't see a route that say "hey route all 2001:470:fxxx::/48 to 2001:470:c:1xxx::1/64 on interface ip6tun". Although there is route entry for "2001:470:c:1xxx::/64 dev ip6tun metric 256" and "2000::/3 dev ip6tun metric 1024" that why I thought "ip -6 r add default via 2001:470:c:1xxx::1/64 dev ip6tun" would do that... but... it won't accept my line.
